Help needed to understand Location-wise Outage details

Help needed to understand Location-wise Outage details

Hi,

Just trying the 24x7 for a month and not sure how to understand the daily reports when it comes to Location-wise Outage details.

For instance I get a report indicating HomePage - Availability Summary Report 
100% Availability      0 Mins 0 Secs for Total Outage Durations and        0 Number of Outage.

I am happy to see that but when I read the report further below I see:

Location-wise Outage Details  
LocationLocation Down DurationDown Duration AvailabilityAvailability (%) (%) DowntimesDowntimes
California - US 0 Mins 0 Secs 100 0
New Jersey - US 0 Mins 0 Secs 100 0
Seattle - US 0 Mins 0 Secs 100 0
Virginia - US 21 Mins 16 Secs 98.52 1
Atlanta - US 0 Mins 0 Secs 100 0
Toronto - CA 0 Mins 0 Secs 100 0

The Virginia 21 Mins outage means the system in Virginia was down or from Virginia my HomePage was not reachable ?

Not sure how to read that portion of the report.

Many thanks for helping,
John
